Abstract

A method was disclosed for pulling a tubular out of a subterranean well. The method including the steps of:i) lowering a work string into the subterranean well, the work string comprising a perforating tool for perforating the tubular, and a tubular pulling tool configured to engage and pull tubulars out of the subterranean well;ii) connecting the tubular pulling tool to the tubular and apply a pulling tension to the tubular; iii) activating the perforating tool to form plurality of perforations extending from an inner wall of the tubular through a material deposited in an annulus defined between the tubular and an outer tubular while the applied pulling tension to the tubular is maintained;iv) immediately upon activating the perforating tool and while maintaining pulling tension to the tubular, pulling the tubular on the work string out of the subterranean well;wherein a cut in the tubular is formed prior to step iii) or simultaneously with step iii); and wherein the cut is arranged such that the tubular can be pulled out of the subterranean well during step iv). Further, a system for pulling a tubular was also disclosed.

Claims (15)

Claims
1. A method for pulling a tubular (2) out of a subterranean well (100), the method comprising the steps of: v) lowering a work string (7) into the subterranean well (100), the work string (7) comprising a perforating tool (8) for perforating the tubular (2), and a tubular pulling tool (6) configured to engage and pull tubulars (2) out of the subterranean well; vi) connecting the tubular pulling tool (6) to the tubular (2) and apply a pulling tension to the tubular (2); vii) activating the perforating tool (8) to form plurality of perforations (10) extending from an inner wall of the tubular (2) through a material deposited in an annulus (3) defined between the tubular (2) and an outer tubular (1) while the applied pulling tension to the tubular (2) is maintained; viii) immediately upon activating the perforating tool (8) and while maintaining pulling tension to the tubular (2), pulling the tubular (2) on the work string (7) out of the subterranean well (100); wherein a cut (9) in the tubular (2) is formed prior to step iii) or simultaneously with step iii); and wherein the cut (9) is arranged such that the tubular (2) can be pulled out of the subterranean well (100) during step iv) .
2. The method according to claim 1, wherein the work string (7) further comprises a tubular cutting tool configured for forming the cut on the tubular (2).
3. The method according to claim 1, wherein the perforating tool is configured for forming the cut on the tubular (2).
4. The method according to any of claims 1-3, wherein the pulling tool is a down hole jacking tool (14).
5. The method according to any one of the preceding claims, wherein the work string (7) further comprises a surge tool (13).
6. The method according to claim 4, wherein the surge tool (13) comprises a fluid chamber (11).
7. The method according to claim 5, wherein the fluid chamber (11) has an internal pressure lower than the pressure in the tubular (2).
8. The method according to claim 5 or 6, wherein the fluid chamber (8) comprises a gas.
9. The method according to any one of claims 4-7, wherein after step iv), activating the surge tool (13).
10 The method according to claim 1, wherein before step i), installing a seal area below the tubular that is removed.
11. A system to pull a tubular (2) out of a subterranean well (100), comprising a work string (7) comprising: a perforating tool (8) arranged to form a plurality of perforations (10) through the tubular (2) and into an annulus (3) upon activation; a tubular pulling tool (6) configured pull a tubular (2) out of the subterranean well by applying a pulling tension to the tubular (2); a means to create a weakness in the tubular (2) by forming a cut (9) in the tubular (2); wherein the tubular pulling tool (6) is arranged to maintain tension on the tubular (2) while the perforating tool (8) activates.
12. The system of claim 11, wherein the means to create a weakness in the tubular (2) is a cutting tool or an arrangement on a portion of the perforation tool.
13. The system of any one of claims 11-12, further comprising a surge tool (13) comprising a fluid chamber with an internal pressure that is lower than the well pressure and the pressure in the annulus (3).
14. The system according to claim 12, wherein the perforating tool (8) comprising one or more perforating guns.
15. The system according to any one of claim 11-14, wherein the cut (9) is formed before or during the activation of the perforating tool (8)
